Nick - when you say 'Custom Styles' do you really mean 'Custom' because that is the name of a specific small group of styles will need to end up in the lower second right rhythm group, and have a seperate method of loading. If you just mean .cmp styles of which there are hundreds if not thousands - I've produced tons myself for specific songs, then to be honest there is no better way than transferring them a few at a time via a floppy disk.
